Marpet-g FS transparent sheet is easy to handle and very suitable for fabrication, heating and vacuum forming particularly at lower temperatures. It has a wide window of processing conditions enabling complex shapes, whilst maintaining good impact strength. Always ensure adequate allowance for thermal expansion.
FABRICATION
Marpet-g FS can be sawn using standard hand tools, circular saws and band saws with carbide-tipped blades for a clean finish. Ensure that the blade is sharp and the material is clamped to prevent vibration which may result in cracking. Marpet-g FS is notch sensitive which can adversely affect the mechanical properties of the material.
SAWING
When drilling Marpet-g FS it is recommended to use drill bits designed for plastics. To avoid overheating, it’s best to use compressed air or wide and highly polished flutes. To prevent vibration, which may result in cracking, it’s recommended to clamp the part securely.
DRILLING
Following cutting, a good edge finish can be obtained using a suitable polishing paste in conjunction with a medium density Reiter wheel, followed by a soft fabric polishing wheel without paste.
EDGE FINISHING
Marpet-g FS can be printed with standard screen and digital printers in conjunction with inks that are suitable for use with thermoplastic co-polyesters. It’s recommended to protect the ink from scratches by applying a light coat of clear lacquer. Prior to printing ALWAYS clean the surface with a soft cloth and use ionized air to clear dust.
PRINTING
Marpet-g FS is resistant to many chemicals and atmospheric pollutants. Contact with solvents must be avoided.
CHEMICAL RESISTANCE
Marpet-g FS can be die-cut, with excellent results on thinner sheets. Sharpened steel blades up to 2.5mm can be used. The back board must be correctly aligned for a clean cut, with the blade completely traversing the sheet to avoid notches. Ensure adequate allowance for thermal expansion.
DIE STAMPING
Marpet-g FS is suitable for cold and hot bending techniques. Cold bending is ideal to create simple shapes. It is recommended to heat sheets above 3mm to produce more complex shapes. The best result is obtained by heating the sheet on both sides using an electric heater. When the optimum temperature is reached (+105°C) the sheet can be bent.
BENDING
Marpet-g FS can be easily thermoformed using general forming techniques including thermosforming, vacuum forming and line bending. Marpet-g FS does not require pre-drying and forms between 120-160°C.
THERMOFORMING
TYPICAL PROPERTIES OF PETg (POLYETHYLENE TEREPHTHALATE GLYCOL COMONOMER) RESIN
Bonding Marpet-g FS can be achieved using suitable adhesive tape, mechanical fixing or welding. When using adhesives ensure they’re chemically compatible with PETg. Adhesive types such as polyurethanes and two-component acrylics give good results.
